are guided in a vertical plane in such a man- I ner that they moveparallel. to themselves at the times when the feet carried by them arenearing the ground line and preferably also when they are rising fromit.

The invention is applicable bothto self propelled and to other vehicles.

Figures 1 to 7 show one method of carrying out the invention. Fig. 1 isaside elevation of a chain of feet 'on one side of the vehicle togetherwith the mechanism for controlling them. Fig. 2 is a side elevation(partly in section on the line 22 Fig. 3) of one end of this chain to alarger scale.

Figs. 3, 4 and5 are sections on the lines 3-3, (and a small portion onthe line rierswith'its foot, and Fig. 7 is a section on 4"4") and 5 -5Fig. 2. Fig. 6 is a lon-' gitudinal vertical section of one of thecarthe line 7'7Fig. 6. Figs. 8 and 9 show a modification. Fig. 8 beingapart side ele- 'vation and Fig. 9 a part end elevation.

Figs. 10 and 11 show another modification.

. Fig. 10 being a part side elevation and Fig.

11 a part end elevation. Figs. 12 to 15 show another modification. F ig.12 being a side elevation of one end of the chain of feet, Fig. 13 aplan of one of the foot carriers with its two pair of sledges, Fig. 141a part section on the line 1414 Fig. 13, and Fig. 15 a section of one ofthe. sledges to a somewhat larger scale.

In Figs. 1 to 7, :1 is a frame supporting springs 2 carrying axles 3fixed to the body of the vehicle which is not shown. A single axle 3maybe employed in place of two and the frame 1 may indeed be connected tothe body in any ordinary way. 4 and 5 are two sets of rails fixed to theframe 1 Specification Letters Patent.

At the points correspondingto the places where the feet. are just above the ground the rails 4' and5, are at different levels as is clearly shown at Figs. 1 and 5, so thatthe f carriers are kept horizontal in spite of the fact that the railsare inclined. The lower members of the guides or rails incline down Wardand backward at their front ends and.

their active surfaces are the same distance apart measured horizontallythroughout the greater part of their inclined lengths.

The guides act on the carriers at two points in their length the linejoining the two ends being at a constant-angle to the verticalthroughout theentire' length of the inclined guides. The carriers. 6 areconnected together by links 9 formingendless chains. 10 are a third pairof wheels on each of. the carriers 6, theiraxle runs in bearings 11 freeto slide in slots 6*in the frame of the carrier and acted on by thesprings 12 (Fig. 5) in such manner as to press the wheels 10' againstthe rails 13 fixed to the frame 1 and thus keep thecarrier steady durinits movement. Thebearings 11 thus constitute slides on the carrierswhich are free-to move transversely to thembut are prevented by thesides of the slots 6" from moving lon'gi tudinally to them. The rails 13form guides for -these slides. 14 are sprocket wheels at the two ends ofthe frame 1', their teeth pass between adjacent carriers 6 and engagewith the tubes 15 whichcontain'the axles '16 of the wheels 7 .and' 8;The bearings 17 ofth'e; axles 18 of the sprocket. wheels 14 are free to'move in guides 19 in the frame land are acted on by screws 20 sothatany wear in the chains of links 9 can be taken'up.

The rails '45- and 5 are made telescopic 'to allow of this 'movement asis shown at Fig. 2 and in the'section on the line 4"-,4". In the caseiofself propelled vehicle's one of the'axlesis driven. Each foot consistsof a plate 21 havin a flange-22 projecting from its upper sur ace andhaving fixed to its grating 23 containing r under, side a cellularblocks 24 of indiarub er, wood or like ma terial. 25 is a plate fixed-t0'the flange 22 v and forming aguide for the flange 26 of a,

"cup 27 which works on a bulb 28 fixed to the frame, of the carrier. Avery smalllon- 'tudinal play but a considerable transverse pivot pinworking in slots 30 in the bulb 28 play is allowed to the flange 26. "29is a serve to limit'themovement'of the wheels 7 and 8 away from therails 4 and 5. In other respects the arrangement is similar to thatshown at Figs. 1. to 7.

In the modification shownat Figs. 10 and 11, the wheels 10 pivoted tothe carriers are i replaced by endless chains 33 of balls or rollersrunning on the rails 13. 34 are blocks bearing on thechain's 33 andconnected tothe carriers ,by springs 35 and llnks 36. Theblocks 34therefore constitute slides on the carriers which are free to movetransversely to them but are prevented by the links 36 from movinglongitudinally to them. The springs 35 serve the same purpose as thesprings 12 namely that of keep- ,parts 39,39

ing the wheels 7 and 8 in contact with therails 4 and '5.

The arrangement shown at Figs. 12 to 15 is a'further modification in thesame direction, the wheels 7 and 8 (shown in Figs. 8

and 9) being replaced by endless chains 37 and 38 of balls or rollers.The chains 33 are retained but the blocks 34, springs 35 and .l1nks36are replaced by sledges made in two forced apart by the springs 40.

ofthejoot carrier and the part 39 is the slide upon it. The working ofthis arrangement is exactly the same as that of the and 5 acting on thefoot carriers at the ends of their axles through the mtervention of thechains 37 and 38 and the sledges 39 in What I claiin 151; 1"
